By which I mean time without the kids, work or chores?
We have a 5 year old and a 3 year old, I work 4 days a week and have the 3 year old on my non working day.
I think in total, I get maybe an hour a week each weekend, evenings are sort of free time but do involve cooking dinner, bits of life admin, sometimes catching up on work.
I feel like that's not very much but maybe it's normal?
